Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning equipment technology, and in particular to a cleaning trolley for pipeline cleaning. Background Technology

[0002] Large pipelines (such as industrial material conveying pipes and municipal drainage pipes) are prone to accumulating dirt, clumps, or biofilms inside. Traditional manual cleaning methods are inefficient and costly. Existing pipeline cleaning equipment mostly uses a single rotating brush or high-pressure water jet, which still requires manual intervention to clean the inner walls of the pipeline. Utility Model Content

[0003] This application addresses the shortcomings of the prior art by providing a compact and efficient cleaning cart. When using a vertical brush head, it can perform rapid cleaning as the cart moves quickly, and when using a circumferential brush head, it can perform targeted cleaning of specific areas as the cart moves slowly.

[0004] The technical solution adopted in this utility model is as follows: A cleaning trolley for pipe cleaning includes a mobile trolley with an installation platform at its front. A cleaning mechanism is fixed on the installation platform. The cleaning mechanism includes a drive unit mounted on the installation platform, a cleaning turntable connected to the drive end of the drive unit, and a cleaning brush head mounted on the cleaning turntable. A spraying mechanism is also provided on one side of the mobile trolley, through which the mobile trolley sprays cleaning liquid onto the cleaning brush head.

[0005] Furthermore, the drive unit includes a bearing bracket, one end of which is fixed with a servo motor and the other end of which is fixed with a bearing seat. A spindle is rotatably mounted on the bearing seat, one end of which is connected to the drive end of the servo motor and the other end of which is connected to the cleaning turntable.

[0006] Furthermore, the cleaning turntable has a multi-spoke disc-shaped cross-section, and the surface of the cleaning turntable is evenly distributed with multiple brush holes, and the circumference of the cleaning turntable is provided with grooves.

[0007] Furthermore, the cleaning brush head is disposed within the brush hole or arranged in the groove in the form of a ring-shaped brush head.

[0008] Furthermore, the mobile trolley includes a trolley chassis, with a driven wheel set at the front and a driving wheel set at the rear. A drive motor is installed inside the trolley chassis, and the drive end of the drive motor transmits torque to the axle of the driving wheel set through chain transmission.

[0009] Furthermore, the spraying mechanism includes a truss, with two sets of guide rails symmetrically arranged below the truss, and a spraying bracket slidably arranged between the guide rails, with multiple sets of spraying pipes arranged on the spraying bracket.

[0010] The advantages of this utility model over the prior art are as follows: 1) High-efficiency integration: It organically combines mobile walking and rotary cleaning, and by configuring vertical and circumferential brush heads, it can achieve rapid cleaning and localized key cleaning, realizing the automation and continuous cleaning of the inner wall of the pipe, and significantly improving cleaning efficiency.

[0011] 2) Structural Optimization: The spraying mechanism is independently installed on the ground, significantly reducing the load on the mobile trolley, simplifying its structure, and improving its passage through the pipeline and operational stability. Entering the spraying mechanism once before cleaning ensures the brush heads are covered with cleaning solution. Attached Figure Description

[0014] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0015] This invention provides a cleaning trolley for pipeline cleaning, aiming to solve the problem of low efficiency in manual cleaning of the inner walls of large pipelines in the prior art.

[0016] like Figures 1 to 5 As shown, a cleaning trolley for pipe cleaning includes: Mobile trolley 1: serving as the main body for carrying and moving. The mobile trolley 1 includes a trolley chassis 11. A driven wheel set 12 is provided at the front of the trolley chassis 11, and a driving wheel set 13 is provided at the rear. A drive motor 14 is provided inside the trolley chassis 11. The drive end of the drive motor 14 transmits torque to the axle of the driving wheel set 13 through a chain transmission mechanism, driving the entire trolley to move along the inner wall of the pipe.

[0017] Mounting platform 2: Fixedly installed at the front of the mobile trolley 1 (front end in the direction of travel) to support the cleaning mechanism 3.

[0018] Cleaning mechanism 3: Fixed on the mounting platform 2. The cleaning mechanism 3 includes: Drive unit: provides rotational power. Specifically, it includes a bearing bracket 311, one end of which is fixed with a servo motor 312, and the other end is fixed with a bearing housing 313. A main shaft 314 is rotatably mounted on the bearing housing 313, and one end of the main shaft 314 is connected to the drive end of the servo motor 312 through a coupling or reducer.

[0019] Cleaning turntable 32: Connected to the drive end of the drive unit spindle 314 (i.e., the other end of the spindle 314), and driven to rotate by a servo motor 312. The cleaning turntable 32 is designed as a disc-shaped cross-section structure with multiple spokes 321 (i.e., a frame-type disc supported by several spokes 321 in the circumferential direction), which has good rigidity and lightweight effect. Multiple brush holes 322 are evenly distributed on the surface of the cleaning turntable 32. In addition, an annular groove 323 is formed on the circumferential edge of the cleaning turntable 32.

[0020] Cleaning brush head 33: Set on the cleaning turntable 32. There are two preferred installation methods: First, the cleaning brush head 33 (usually a bundle or columnar bristles) is directly inserted and fixed within the brush hole 322; second, the cleaning brush head 33 is in the form of a ring-shaped brush head (i.e., a ring-shaped distribution of bristle bundles), arranged and fixed within the groove 323 on the circumferential edge. The brush head material can be nylon, steel wire, or composite materials, depending on the cleaning requirements.

[0021] Spraying mechanism 4: Independently mounted on the ground (or adjacent to the outside of the pipe) on one side of the mobile trolley 1, and does not move with the trolley. It is used to precisely spray cleaning fluid (such as water, detergent solution, or disinfectant) onto the rotating cleaning brush head 33. Spraying mechanism 4 includes: Truss 41: As the main support structure, it is erected above / to the side of the inlet of the pipe to be cleaned or the work area.

[0022] Guide rail 42: Two sets of guide rails 42 are symmetrically arranged below the truss 41 and laid parallel to the pipe axis.

[0023] Spray bracket 43: Slidably mounted between two sets of guide rails 42, capable of reciprocating along the guide rails 42. Multiple sets of spray pipes 44 are mounted on the spray bracket 43, facing the working area of ​​the cleaning brush head 33 inside the pipe. The spray pipes 44 are connected to an external pumping system, capable of spraying mist or columnar cleaning liquid.

[0024] Working principle of the invention: Driven by the drive motor 14 and chain drive, the mobile trolley 1 moves along the inner wall of the pipe.

[0025] As the trolley moves forward, the servo motor 312 of the cleaning mechanism 3 drives the cleaning turntable 32 to rotate at high speed through the main shaft 314, which in turn drives the cleaning brush head 33 on it to scrub the inner wall of the pipe.

[0026] Before the trolley enters the pipeline, the spray pipe 44 of the spray mechanism 4 continuously sprays cleaning liquid onto the rotating cleaning brush head 33, which wets, washes away dirt, cools the bristles, and washes away the dirt left by the previous brushing.

[0027] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
